Crafted with EdrawMax, this *Thread Module Code Call Flow Template* outlines the hierarchical code execution logic. It shows how *threads/main.cc*’s *main()* triggers functions in *threads/kernel.cc* (e.g., *Kernel()*, *Initialize()*, *ExecAll()*), and traces paths like *Exec()* leading to *ForkExecute()* and subsequent calls to *userprog/addrspace.cc*’s *Load()*/*Execute()*. Also detailing threads’ lifecycle functions (e.g., *Finish()*, *Sleep()*), it’s ideal for developers to analyze code dependencies, debug, or optimize thread - related software architectures, clarifying how different modules and functions collaborate in a threaded program.
